Product Review (submitted on August 10, 2012):
This is unit is to power-heads what LEDs were to lighting! Amazing versatility in volume and velocity of water. Controller is absolutely awesome. My fish and corals LOVE it!! I know it's pricey, but do yourself and your fish a huge favor and get this unit . . . it works!!
